Assessment of the usage of historical materials and of the damage situation at the reference sites

Dependant on the function of the mortar the Nabateans used various kinds of binding media (gypsum and/or lime) at Qasr al Bint and various kinds of aggregates and admixtures (limestone, basalt, pumice, fibres) at the Great Cathedral in Bosra. This gives a detailed impression of the advanced building technology in Nabatean times. Soluble salts transported into the wall by rising damp or by wind deposit are the most severe threats to these ancient materials. At Qasr al Bint the problem is increased by the partial dissolution of historical gypsum mortars and their recrystallization within the adjacent building stone. The mapping and testing campaign provides spatial information of the various materials and of the damages at the building. This information can be used by archaeologists e.g. to discern various construction periods and by the concerned institutions and/or restorers as a pre-information for the formulation of a preservation concept.
